Its worth mentioning that this is not a good time at all for companies to be designing new nodes.
A lot of microcontrollers are very difficult to get hold of these days. For the example mentioned above, I wanted to use an ATmega4808 as it has more memory than the more familiar ATmega328P a device which can be borderline, memory wise, for some applications.
Currently Farnell\Element 14 dont expect supplies of the ATmega4808/9 until early May 2023.
Hello, I made a lot of āuselessā DIYs , recently Iām playing with Seed-E5 Lora SOC modlue + BME680 T/H/P/AQI gas sensor, together with TTN and cayenne_lpp. I saw your post just now, and checked my DIY sensor found it quite sensitive to matchesā smoke. Maybe this time my DIY is not useless, but can helps you.
